No
The summary describes software used in the design and manufacture of patient-specific cutting blocks based on imaging scans, but there is no mention of AI or ML being used in this process. The focus is on software validation and extending shelf life.
No.
The device is described as "patient-specific surgical instrumentation to assist in the positioning of total knee replacement components intra-operatively and in guiding the marking of bone before cutting." It is a tool for surgery, not a device that directly treats or prevents a disease or condition.
No
The device is described as "patient-specific surgical instrumentation" used to assist in "positioning of total knee replacement components intra-operatively and in guiding the marking of bone before cutting." It is an instrument for surgical guidance, not for diagnosing conditions.
No
The device description explicitly states that the software component is used in the design and manufacture of "Patient Matched Cutting Blocks," which are physical surgical instruments. The 510(k) is seeking clearance for the software component and an extension of the shelf life of the physical cutting blocks.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is "patient-specific surgical instrumentation to assist in the positioning of total knee replacement components intra-operatively and in guiding the marking of bone before cutting." This describes a surgical tool used during a procedure, not a device used to examine specimens in vitro (outside the body) to provide diagnostic information.
- Device Description: The description focuses on the software component used in the design and manufacture of the cutting blocks, which are then used in surgery.
- Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Providing diagnostic information about a patient's health status
- Using reagents or assays
The device is a surgical aid designed to improve the accuracy of a surgical procedure based on pre-operative imaging. This falls under the category of surgical instrumentation, not in vitro diagnostics.

§ 888.3560 Knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a knee joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a tibial component or components and a retropatellar resurfacing component made of ultra-high molecular weight polyethylene. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II.

Dear Brad Sheals:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820);
